Abstract
The present invention is directed towards a motorcycle or off-road use with an improved engine, air inlet, exhaust and engine control management. The engine is an improved four-stroke engine with a monocoque cylinder and crank case. The air inlet has been moved to the head tube of the motorcycle frame. The engine is reverse flow with the exhaust coming out the rear side and being shortened to less than about 50 inches. The engine control management has been modified to include an ignition interrupt, gear based ignition timing and after market tuning capabilities.
